I'm using Eco Ears for my dog to prevent infections and clean his ears. He's a golden retreiver and seems to product a lot more wax than my previous dog (a weimar). The ingredients seem to have been changed since the previous post. The website says it has these ingredients...Nothing I'd want to drink either! but it's working for me and my dog... Denatured Grain Alcohol, Rosemary Extract, Natural Witch Hazel Extract (made from non-petroleum alcohol), Organic Mullein Extract, Vegetable Glycerine, Tea Tree Oil, Polysorbate 20 (food grade), Ionic Silver Solution, Boric Acid.
